- Additional Description of Rooftop Package
The rooftop package, or package unit, is essentially a combination of a chiller and an air handler in a single integrated unit. Rooftop packages perform heating, cooling, filtration, and humidity control functions. The internal components of the unit include an air-cooled chiller, a refrigerant-containing coil, a hot water coil, a fan, a filter, and humidification equipment. In cooling mode, the air-cooled compressor chiller operates and sends refrigerant to the refrigerant coil (evaporator), while the fan, by rotating and passing air around the coil, causes the air temperature to decrease. In heating mode, hot water must be sent from the boiler or wall-mounted package unit to the hot water coil, with the fan rotating to increase the air temperature. The rooftop package also has three air channels: supply air, return air, and fresh air.
Rooftop packages are typically installed in an open area, usually on the roof, and generally have three vents (fresh air intake, return air vent from the building, and the pleasant output air vent from the unit to different areas of the building). Fresh air mixes with return air (recirculated), and after being heated or cooled and passing through the filters within the unit, it exits through the unit’s outlet and enters the building through ductwork. Due to the use of a compression refrigeration cycle (similar to chillers, air conditioners, etc.) in this device, its cooling is very comfortable, and due to the use of hot water from the boiler or package unit, its heating is also very pleasant.
- What is a rooftop package or cooling package? A rooftop package is essentially an air conditioning device that is simply a combination of a chiller and an air handling unit, with some components of both removed. The rooftop package has an external unit that performs air ventilation; after the air is conditioned in the external unit, the ventilated air is sent into the environment through ducts. To save energy, rooftop package units have a return air duct to transfer the air from inside the environment back to the external unit for reconditioning before returning it to the environment. The critical importance of this device lies in its ability to supply fresh air. This means the device mixes the return air from the environment with fresh air and again conditions this new mixture before delivering it to our desired location. This device is suitable for public areas with high foot traffic and a need for fresh air, such as conference halls, offices, stores, banquet halls, etc., as well as warehouses that store food and goods, which require air filtration, dehumidification, and fresh air injection to prevent spoilage. What is the difference between a rooftop package and an air handling unit? Rooftop packages and air handling units have many similarities. Both devices are used for air conditioning and both can provide fresh air and air filtration. The main difference between the cooling package and the air handling unit lies in their ability to produce cooling. The air handling unit, also known as an air delivery unit, requires a connection to a separate chiller or condensing unit to perform the cooling function. In other words, the air handling unit alone is not capable of...
